Pneumatic Pressure Standard MC100

The MC100 Series is well-suited for calibration and maintenance of pressure instrumentation. Various pressure instruments such as pressure sensors, industrial transmitters, and pressure switches, as well as sphygmomanometers and other medical devices face severe price competition and demands for improved accuracy.

Silicon resonant sensor

High sensitivity and resolution and superior long-term stability
The vibrators are in a vacuum. This reduces the dispersion of vibration energy. Combined with the superior flexibility of monocrystal silicon, this makes it possible to obtain a high Q value.

Extremely low temperature dependence
Two vibrators are used, and pressure is derived from the difference between the two unique oscillation counts. With this operating structure, it is possible to cancel out external environment influences such as ambient temperature. In addition, the oscillators are in a vacuum, so they are not affected by ambient temperature or humidity.
